Should production transactions abend?

I know of a company that will NOT fix transactions that abend in production. NO time, it doesn't happen all the time... are some of the responses Tech Support gets from the developers. An EMAIL address was set up so the development support staff could be given notice when abends happen. No one has been asked to be put into that mailing list.
I would disable the transaction(s) until someone agrees to work on them. even if that meant some loss of work.

How does anyone else feel?
